Q. Which of the curves in figure represents the relation between Celsius and Fahrenheit temperatures
A) 1
B) 2
C) 3
D) 4
Explanation
(a) $\frac{C}{5} = \frac{F - 32}{9} \Rightarrow C = \left( \frac{5}{9} \right)F - \frac{20}{3}.$ Hence graph between $℃$ and $℉$ will be a straight line with positive slope and negative intercept
